0.11 per yard.
Step-by-step explanation:
3x + y=5
6x -2y=10 Is it consistent/non consistent and need solution
once i see how to do one ill understand how to do others. thank you
Answer: These are non- consistent and can be solved. The signs of the y terms are the opposite.
Step-by-step explanation: If the signs are the same, and all the terms of one equation are multiples of the other, they are identies, with infinite solutions. We can solve this system by multiplying the first equation by 2, adding the equations to cancel the y terms, and solve for x.
2(3x+y=5) becomes
6x +2y= 10 Add it to the other equation
6x -2y= 10 We are left with
12x = 20 Solve for x
x = 5/3 Substitute for x and solve for y.
3(5/3) + y = 5
5 + y = 5. Subtract 5 from both sides.
y = 0
The solution to this system is (5/3 , 0)

Use the drawing tool to form the correct answer on the provided graph plot the x-intercept y-intercept and axis of symmetry for the function below g(x) = x2+4x+3
Answer:
x-intercepts: x =-1, x=-3 when y=0
y-intercept, y=3, when x =0
axis of symmetry x = -2
Step-by-step explanation:
We are given the function: [tex]g(x) = x^2+4x+3[/tex]
We need to draw the graph for
x-intercept y-interceptaxis of symmetryof the given function.
x-interceptFor finding x-intercept put y=0, in the given function, we will put g(x) =0
We know that: g(x)=y
[tex]y=x^2+4x+3[/tex]
Putting y=0, we get:
[tex]0=x^2+4x+3[/tex]
Now, we need to solve the equation by factorization, to find value of x
[tex]0=x^2+4x+3\\We\:can\:write\\x^2+4x+3=0\\x^2+3x+x+3=0\\x(x+3)+1(x+3)=0\\(x+1)(x+3)=0\\x+1=0\:or\:x+3=0\\x=-1\:or\:x=-3[/tex]
So, we get x-intercepts: x =-1, x=-3 when y=0
y-interceptFor, finding y-intercept, put x =0
Putting x=0
[tex]g(x)=x^2+4x+3\\We\:know\:g(x)=y\\y=x^2+4x+3\\y=(0)^2+4(0)+3\\y=3[/tex]
So, we get y-intercept, y=3, when x =0
Axis of symmetryThe formula used to calculate axis of symmetry is: [tex]x = \frac{-b}{2a}[/tex]
We have b=4 and a = 1
Putting values and finding axis of symmetry
[tex]x =-\frac{b}{2a} \\x=-\frac{4}{2(1)}\\x=-2[/tex]
So, we get axis of symmetry x = -2
We will also be requiring vertex of the function:
We can find h = -b/2a (same as axis of symmetry) we get h =-2
k can be found as k=f(h)
Put h=-2 in the function:
g(-2)=(-2)^2+4(-2)+3
g(-2)=4-8+3
g(-2)=-1
So, we get k = -1
The vertex (h,k) is (-2,-1)
Now, the graph is attached in figure below.

The town librarian bought a combination of new-release movies on DVD for $20 and classic movies on DVD for $8. Let
x represent the number of new releases, and let y represent the number of classics. If the librarian had a budget of
$500 and wanted to purchase as many DVDs as possible, which values of x and y could represent the number of
new-release and classic movies bought?
O x = 8, y = 45
O x = 10, y = 22
O x= 16, y = 22
O x = 18, y = 18
Answer:
Step-by-step explanation:
he is right i got a 100 in the test
The number of new-release movies on DVD is 16 and the number of classic movies on DVD is 22 option third x= 16, y = 22 is correct.
What is linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
New-release movies on DVD for $20 and classic movies on DVD for $8
x - the number of new releases,
y - he number of classics.
20x + 8y = 500
or
5x + 2y = 125
Using trial and error method:
Plug x = 16 and y = 22
5(16) + 2(22) = 125
= 80 + 44
= 124
Nearest to 125
Thus, the number of new-release movies on DVD is 16 and the number of classic movies on DVD is 22 option third x= 16, y = 22 is correct.

Find the quotient of 4.13 × 10^−8 and 0.04 × 10^5. In two or more complete sentences, explain each step in your calculations. Include the quotient as part of your final answer.
Answer:
[tex]q=1.03\times 10^{-11}[/tex]
Step-by-step explanation:
Given that,
First number [tex]=4.13\times 10^{-8}[/tex]
Second number [tex]=0.04\times 10^{5}[/tex]
We need to find the quotient of first and the second number. It can be calculated by taking [tex]=4.13\times 10^{-8}[/tex] at numerator and [tex]=0.04\times 10^{5}[/tex] at denominator such that,
[tex]q=\dfrac{4.13\times 10^{-8}}{0.04\times 10^5}\\\\=\dfrac{4.13}{0.04}\times 10^{-8-5}\\\\=103.25\times 10^{-13}[/tex]
or
[tex]q=1.03\times 10^{-11}[/tex]
So, the final answer is [tex]1.03\times 10^{-11}[/tex]

Derive an expression for total pay
Represent the number of hours with h.
For Hamda and Layla, their pay for h hours is:

For Hamda, we have:
[tex]Hamda : 25 + 10.50 * h[/tex]
[tex]Hamda : 25 + 10.50 h[/tex]
For Layla, we have:
[tex]Layla: 18 + 14.25 * h[/tex]
[tex]Layla: 18 + 14.25 h[/tex]
For h hours, the company will pay:
[tex]Company: Hamda + Layla[/tex]
[tex]Company: 25 + 10.50h + 18 + 14.25h[/tex]

Explanation:
VX is a midsegment and it is half as long compared to the parallel side UY. This means UY is twice as long compared to VX
UY = 2*(VX)
s = 2*(s-37)
s = 2s - 74
s-2s = -74
-s = -74
s = 74
This makes UY be 74 units long
So VX = (1/2)*UY = 0.5*74 = 37
Answer:
37
Step-by-step explanation:
The midsegment theorem states that a midsegment is half the measure of the line it is parallel to (the base). So VX is 1/2 of UY. So:
2(s-37)=s
2s-74=s
s=74
VX= 37

A house sits on a rectangular piece of land. Two of the sides measure 104 feet each. If all four sides add to 576 feet, how long is each of the other two sides? Write and solve an equation.
Answer:
Each of the other side is 184 feet.
Step-by-step explanation:
Given that:
Length of two sides each = 104 feet
Total length of all sides = 576 feet
Let,
x be the length of other one side.
Length of other two sides will be 2x.
Total length of sides = 2x + 2(104)
576 = 2x + 208
2x = 576 -208
2x = 368
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{368}{2}\\x=184[/tex]
Hence,
Each of the other side is 184 feet.
